Trim: AMG Line

Comes with plenty of luxury gizmos, including adaptive LED headlights, leather seats, part-electric front seats with lumbar adjustment and heating, climate control, parking sensors front and rear, a rear-view camera and power-folding door mirrors. Infotainment wise, you get sat-nav, a DAB radio and Bluetooth, all operated via the 12.3in central screen, with another 12.3in screen adjacent to it in place of analogue instruments. Safety aids include automatic emergency braking and lane assist, with blindspot monitoring an option.

Engine: CLS 400d 4Matic

This uses the same 2.9-litre straight-six engine as the 350d but with power boosted to 335bhp – and it’s a belter. In fact, it’s one of the best diesel engines currently on sale; not simply because performance is mighty – delivering effortless pace with just a tickle of the accelerator that turns ballistic when you hoof it – but also because the engine revs keenly and stays pleasantly smooth all the way to its limiter. The standard nine-speed auto gearbox is smooth and responsive, too.
